What is the Black Knight satellite? It is a mysterious satellite, of unknown origin, discovered in 1960 which shadowed Sputnik. It is believed to have been of extraterrestrial origin, and signaled back old radio waves from the 1920s and 1930s before it disappeared.
EXOSAT remained in orbit from 1983 to 1986. A much larger X-ray astronomy satellite was launched on June 1, 1990, as part of a cooperative program involving the United States, Germany, and the United Kingdom. This satellite, called the RÃ¶ntgensatellit (ROSAT), had two parallel grazing-incidence telescopes. One of them, the X-ray telescope, bore many similarities to the equipment of the Einstein Observatory but had a larger geometric area and better mirror resolution. The other operated at extreme ultraviolet wavelengths.
